转发: segment fault for fiasco-ux

[halo.duan]

Hi
the linux kernel is 2.6.15-1.2054-FC5, gcc is 4.1.0 20060304.
code is the latest update.

following is screen copy of gdb

Fiasco-UX on Linux 2.6.15-1.2054_FC5 (i686) Mapped 64 MB Memory + 0 KB
Framebuffer + 0 MB Input Area on FD 6

Loading Module 0x00090000-0x00099380 [sigma0] Loading Module
0x00120000-0x002b09e4 [roottask]

Bootstrapping...

Welcome to Fiasco(ux)!
DD-L4(v2)/x86 microkernel (C) 1998-2006 TU Dresden
Rev: Fri Dec  8 18:40:04 2006 compiled with gcc 4.1.0 for Intel Pentium III

Detaching after fork from child process 2486.

Program received signal SIGSEGV, Segmentation fault.
Dirq::alloc (this=0xd242d, t=0xd7b80, ack_in_kernel=-1)
    at /home/halo/l4/kernel/fiasco/src/drivers/ux/processor-ux.cpp:62
62        asm volatile ("cli" : : : "memory");
(gdb)


according to the fiasco-ux documents, the SIGSEGV must be handled by fiasico
registered handler. but I don't know why fiasco generate such enomous number
of SYSSEGV.

so what's happened


best regards
